... two prostitutes came to the king (Solomon) and stood before him. One of them said, 'My lord, this woman and I live in the same house. I had a baby while she was there with me. The third day after my child was born, this woman also had a baby. We were alone; there was no one in the house but the two of us. During the night this woman's son died because she lay on him. So she got up in the middle of the night and took my son from my side while I your servant was asleep. She put him by her breast and put her dead son by my breast. The next morning, I got up to nurse my son—and he was dead! But when I looked at him closely in the morning light, I knew that it wasn't the son I had borne.' The other woman said, 'No! The living one is my son; the dead one is yours.' The king said, 'Bring me a sword.' So they brought a sword for the king. He then gave an order: 'Cut the living child in two and give half to one and half to the other.' The woman whose son was alive was filled with compassion for her son and said to the king, 'Please, my lord, give her the living baby. Do not kill him; she is his mother.'

In a competitive market, the market demand is Qd = 60-6P and the market supply is Qs = 4P. A price ceiling of $3 will result in a -shortage of 30 units -shortage of 15 units -surplus of 30 units -surplus of 12 units
shortage of 30 units Qd=60-6(3)= 42; Qs=4(3) =12 42-12=30
Consider the monopoly in the figure below with price regulated at $2 per unit. The regulated price will result in a: surplus of 2 units. shortage of 2 units. surplus of 5 units. shortage of 5 units
shortage of 5 units
A relationship-specific exchange occurs when a partnership is dissolved. specialized investments are important. a partnership is initiated. shareholders receive dividends
specialized investments are important.
The presence of minimal specialized investments relative to contracting costs suggests that the optimal input procurement method is: spot exchange. vertical integration. contract. vertical integration or contract
spot exchange
As additional consumers obtain the benefits of a pure public good, such as national defense, the benefits to the existing consumers will: decrease. increase. stay the same. increase in the short run, but decrease in the long run.
stay the same.
If the cross-price elasticity between goods X and Y is positive, we know the goods are: inferior goods complements inelastic. substitutes.
substitutes
Costs that are forever lost after they have been paid are: production costs. fixed costs. sunk costs. variable costs.
sunk costs
In order to minimize the cost of producing a given level of output, a firm manager should use more inputs when: that input's price rises. that input's price falls. that input's price remains the same. the prices of other inputs fall.
that input's price falls.
The principal's goals are NOT in line with the goals of: any other principal. the agents. the firms. the consumers
the agents.
if demand is perfectly inelastic, then: -the own price elasticity of demand is infinite in absolute value -a small increase in price will lead to a situation where none of the good is purchased -the demand curve is vertical -none of the statements is correct
the demand curve is vertical
Other things held constant, the greater the price of a good -the higher the quantity demanded -the greater the consumer surplus -the lower the consumer surplus
the lower the consumer surplus
Suppose a monopolist has positive fixed costs and constant marginal costs. If the government regulates a monopoly's price to marginal cost, in the long run: the monopolist will earn a profit if ATC > MC. the monopolist will exit the industry. the monopolist will earn a profit if ATC > P. the monopolist will earn zero profits.
the monopolist will exit the industry.
Fixed costs exist only in: the long run. capital-intensive markets. the short run. labor-intensive markets.
the short run.
The marginal product of an input is defined as the change in: -average output attributable to the last unit of an input. -total output attributable to the last unit of an input. -total input attributable to the last unit of an output. -average output attributable to the last unit of an output
total output attributable to the last unit of an input.
Accounting profits are:
total revenue minus total cost
To avoid the problem of double marginalization: transfer prices must be set that maximize the overall value of the firm rather than the profits of the upstream division. firms should put more emphasis on vertical integration. firms should engage in two-part pricing. firms should engage in commodity bundling, unless it is possible to engage in either first-or second-degree price discrimination.
transfer prices must be set that maximize the overall value of the firm rather than the profits of the upstream division.
Revenue sharing tries to induce worker effort by linking: worker compensation to profits. worker compensation to revenues. worker output to profits. worker output to revenues
worker compensation to revenues.
A potential problem with piece-rate plans is that: workers will produce a large quantity. workers have no incentive to work hard. it is difficult for managers to control. workers may stress quantity instead of quality.
workers may stress quantity instead of quality
If you advertise and your rival advertises, you each will earn $3 million in profits. If neither of you advertises, you will each earn $7 million in profits. However, if one of you advertises and the other does not, the firm that advertises will earn $10 million and the non-advertising firm will earn $1 million. If you and your rival plan to be in business for 15 years, then the Nash equilibrium is for: you and your rival to not advertise in any year. you and your rival to advertise every year. neither firm to advertise in early years, but to advertise in later years. each firm to advertise in early years, but not advertise in later years.
you and your rival to advertise every year
The exchange rate between the Japanese Yen and the UK Pound is 12.70 ¥/£. It costs $1.72 US to buy a pound. How many Yen does it take to purchase $1 US? ¥21.85 ¥0.05 ¥7.38 ¥0.14
¥7.38
Which of the following profit functions exhibits a Leontief production function? π = P × K0.75L0.50 − 20L − 35K π = P × min(2L, 5K) − 20L − 35K π = P × (3K + 4L) − 20L − 35K π = P × (3K0.5 + 4L0.5) 1/0.2 − 20L − 35K
π = P × min(2L, 5K) − 20L − 35K
Consider a market consisting of two firms where the inverse demand curve is given by P = 500 − 2Q1 − 2Q2. Each firm has a marginal cost of $50. Based on this information, we can conclude that aggregate profits in the different equilibrium oligopoly models will follow which of the following orderings? πBertand > πCollusion > πStackelberg > πCournot πCollusion > πCournot > πStackelberg > πBertand πCollusion > πStackelberg > πCournot > πBertand None of the answers is correct.
πCollusion > πCournot > πStackelberg > πBertand
If a monopolist claims his profit-maximizing markup factor is 3, what is the corresponding price elasticity of demand? −1.5. −2.0. −2.5. −3.0.
−1.5.
In a monopoly where the marginal revenue and price are, respectively, given by $0.50 and $2, the price elasticity of demand is: −0.75. −1. −5/4. −4/3.
−4/3.
Compute the marginal revenue when the price elasticity of demand is −0.10. −9P, meaning marginal revenue is negative and 9 times greater than price. 9P, meaning marginal revenue is positive and 9 times greater than price. −3P, meaning marginal revenue is negative and 3 times greater than price. 3P, meaning marginal revenue is positive and 3 times greater than price
−9P, meaning marginal revenue is negative and 9 times greater than price.
